Nevertheless, you used a sophisticated growing system to do so.

"I give you credit for pleading guilty at the earliest opportunity, your co-operation with police and the fact that you are, until now, a man of good character," Workman added.

In April, Waylett and a friend were arrested after police searched a car he was riding in and discovered eight bags of marijuana and a knife. Police then raided his mother's home and found 10 marijuana plants. The cannabis was reportedly worth approximately $2,900 and was growing under hydroponic lights, next to a PlayStation console.

Waylett's friend, John Innis, who admitted to illegally possessing 11 bags of marijuana and a knife, was fined 500 pounds and sentenced to six weeks' custody in a young offenders' institution, according to Reuters.
